IMPROVEMENT IN METHODS OF ATTACHING HANDLES TO SCRAPERS.

.I'he Schedule referred to inthese Letters Patent and making part of thesanne.

. L-Enwnnn C. Loom), of the city and county of Providence, State ofRhode Island, have invented certain Improvements in Scrapers, of whichthe following is a specification.

The first part ot' my invention relates to so firmly fastening the plateoi' the scraper to the rest of the parts constituting thescraper that itwill not become loosened so easily as in scrapers now generally used.

The second part of my invention relates to the cornhination of the plateof the scraper with the other parts in such a manner that it will beheld firmly in its place when in a position for using, and also that itmay be turned upon an axis so as to enable it to be ground wit-hout thediihculty now experienced.

Figure lis a view with the scraper arranged for scraping.

Figure 2 is a view with the scraper arranged for sharpening.

Figure 3 is a longitudinal section of the scraper.

A represents the plate.

B B, the two nuts, holding plate A firmly by means ofthe two jaws orarms C C extending backward from the plate A.

lC ,C represent the two jaws or armson which the plate A rests.

D represents the hinge on which the arms or jaws C C turn, the hingepassing through theupper end" of the tongue E.

E is the tongue.

I" F are the two holes in the plateA, either of which, in conjunctionwith the hole G, is used to firmly secure the plate A in its place bymeans of a thumb-screw or screws when in position for grinding.

G is the hole in the tongue in conjunction with E F in the plate A, bymeans of which the plate A is held rmly in position with the screw whenfastened for the purpose of grinding.

H H represent the holes at the lower extremity of the jaws or arms C C,through which, in conjunction with the hole I, the screw passes,holding/the arms or jaws C C firmly in their place when the scraper isin position for using.

I is the hole in the lower part of the tongue E, and is used, inconjunction with the holes H- H in the lower Apart of the jaws C (l, ascrew passing through H H and I, holding the jaws O C firmly inposition.

J is thedetachable screw, used in conjunction with either of thel holesF Ill and G o'r H H and I.

The particular differences andadvantages of this scraperover thoseinordinary use are these:

In the ordinary scraper the plate is secured to the handle by only onebolt, and cannot move from its fixed position for the purpose ofgrinding. In this improved scraper the plate'is firmly secured by twobolts to the arms or jaws G O, so that when these jaws ar'e secured tothe tongue E by a screw the plate is firm, and does not 'become loosenedso easily as -by the ordinary method of securing it.

In the ordinary scraper there is considerable diicnlty in grinding it.As it is stationary it is almost impossible to shlarpen it uniformly. Bythe improvement. here madev the plate turns upon a hinge on both sidesof the tongue, so that the edges may be easily placed upon thegrindstone and sharpened equally on all sides. By this means every sidemay be rendered serviceable.

The advantages of' this improvement are obvious at a glance. 4

What I claim, and desire to secure by Letters Patent, is-

lhe combination of a perforated scraper-plate, A, a pair of arms, O O,securely fastened to the same, the arms moving indifferent directions oua hinge, D,

which isv attached to each-'of said arms O O, a hinge,'

D, passing through the head of a tongue, E, the tongue E withperforations to correspond with those of the scraper-plate A, and usedin conjunction withthem, and a thumb-screw, J, or its equivalent,substantially as described and for the purposes set forth.

EDWARD O. LOGKE.
